A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Certain 2025 Heartland Mallard, Prowler, Eddie Bauer and Corterra Travel Trailers have fiberglass walls that are too short to adequately protect the floor decking. These instruction provide for the proper steps to add additional seal to the bottom of the sidewall to prevent any water intrusion.
